CLARENCE RATHBONE, OF ALBANSQNEWV YORK.

DAMPER FOR STOVES AND RANGES.

SPECIFICATION forming part of Letters Patent No. 248,501, dated October18, 1881.

Application filed June 16, 1881.

To all whom it may concern Be it known that I, CLARENCE RATHBONE, of thecity and county of Albany, and State of New York, have invented certainnew and useful Improvements in Dampers for Stoves, of which thefollowing is a specification.

My invention relates to an improvement in themodeofoperatingrollingdampers ofstoves, ranges, 850.; and theobject ofmy improvement is to provide a simple device for producing synchronaland corresponding movements of two adjacent dampers that are ranged onparallel lines, but set apart from each other. This object I attain bymeans of the mechanism illustrated in the accompanying drawings, whichform part of this specification, and in which- Figure 1 is a perspectiveview of the rear portion ofa range containing my improvement, with partsof the top broken away to show the underlying construction; and Figs. 2,3, 4, and 5 are detached details of construction of the dampers andactuating-rod.

The range represented in the drawings is one of the usual construction,having the fire-box at one end, while the opposite end contains twodraft-fines, one descending and the other ascending, connecting with arevertible flue beneath the oven. At its upper end the ascending flueconnects with a horizontal flue formed between the top plate of therange and the top of the oven, and this latter flue communicates withthe outlet-flue leading directly to the escape-pipe at the rear of therange.

One defect com mon to all ranges of this class as heretofore constructedhas had its origin in the contracted and insufficient direct draftopening for the draftcurrents, that pass directly from the fire-box tothe escape-pipe without passing under and back of the oven. Said defeetis inherent in the necessarily peculiar form of the flue-strip thatseparates the flues over the top of the oven, the broken surface of saidfluestrip preventing the formation at an eligible point of a singlesufficient opening; and the use of several openings located at differentpoints of said flue-strip, that run in the same direction, but are notranged on the same line, has heretofore been held as objectionable onaccount of the supposed difflculty of operating at one time and with apositive motion several separate dampers for covering said openings (Nomodel.)

when arranged in the manner above set forth.

My invention remedies the defect above referred to.

In the accompanying drawings, A indicates the top plate of the oven; B,the descending and B the ascending flue, both located at the end of theoven O, the horizontal flue (over the top of the oven) connecting theascending flue B with the escape-pipe; E, the flue-strip for separatingthe flue G from the main flue over the top of the oven. The parts 6 ande of said flue-strip both run parallel to the side of the range, but areplaced at different distances therefrom. F and F are direct-draftopenings, formed respectively in the parts 0 and e of the fiue-stri p E;G, rolling dampers for closing the direct-draft openings. Said dampersare each provided with a cup-shaped protuberance, g, Figs.2, 3, and 4,having a slotted opening,g', formed therein. H is a rod for operatingboth dampers Gr. Said rod has but a single part where it passes throughthe side of the range, but is bifurcated within it, one branch thereofconnecting to the damper for the opening]? and the other to the damperfor the opening F. Each branch is provided with a raised stem, h, (forpassing through the slotted openings 9 of the dampers,) which terminatesin a T-head, h, that engages underneath the protuberance g on thedampers, for the purpose of forming a hinge-like connection between thelatter and their operating-rods.

By my improvement ample openings are formed for thedirect-draft'currents in their passage from the fire-box directly to theescapepipe. The dampers for said openings areadapted to movesimultaneously, and the boiler-hole (not shown in the drawings) over theflue O is not cut off from the heated currents when the direct-draftopenings are thrown open. When required, it is obvious that more thantwo direct-draftopenings may be formed and each provided with anindependent damper connected, as herein described, to a separate branchof a furcated rod, so that a simultaneous movement of all the dampersmay be produced by a single movement of the external handle.

I claim as my invention- 1. The combination, with two or more separateddampers, G, of the furcated rod H, having an independent attachment toeach of said dampers, hut adapted to produce a synehro and fureated rodH, constructed and arranged nous and like movement of allthedampersconin relation to each other to operate as herein IO nected thereto, asand for the purpose herein specified.
